Change the code to :
String line = in.readLine();
while (line != null) {
ress = "<br>" + line;
line = in.readLine();
}
There is only one line to read, and its already read in while(in.readLine() != null).
After this, even if you try to read again using in.readLine(), it will try to read
next line, which is null.
I suggest to use ress as StringBuffer, if you expect more than 1 line and use
ress.append("<br>" + line).
Hope this helps...
Thanks

Subject: trouble with readin value from Runtime.exec(cmd)
Hallo,
I have shell program, which I must call and read its output. On the
console it print some output to console and has some *return value*.
This return value I must read back to java:
The part of code is:
****************************
String ress = "---";
Process p = null;
try{
Runtime r = Runtime.getRuntime();
p = r.exec("cd /usr/local/cai; ./inocucmd -SEC -NEX /tmp/file.pif;
echo $?");
BufferedReader in = new BufferedReader(new
InputStreamReader(p.getInputStream()));
while (in.readLine() != null) {
ress = "<br>"+in.readLine();
}
in.close();
}catch(Exception et){
out.println("Fail: "+et.toString());
}
out.println("<br>result is: "+ress+"<br>");
***************************************************************
but there is no value ... (in.readLine() conatins null)
Is there anything what I not comprehed good? or where can be way?
Thanks
Jiri
